Well heck no the M4 isn't going to outperform those and I presume you mean in power and terminal ballistics. Now a semi and full automatic does out perform a bolt action in putting out fire power and keeping the enemie's heads down. Also that short carbine is better fit to room to room house cleaning then say that long Garand. Like I've said you can't eat your cake and have it too with the M4 carbine.
